KNITTING-MACHINE NEEDLE.

SPECIFICATION forming part of Letters Patent No. 670,886, dated March 26, 1901.

Application filed February 16, 1897. Serial No..623,735. No model.)

To (tZ whom, it IWIfl/Z, concern:

Be it known that I, ELMER E. NEWTON, a citizen of the United States,residing at Franklin, in the county of Merrimack and State of New Hampshire, have invented a certain new and useful Improvement in Knitting-Machine Needles, of which the following is a full, clear, and exact description.

This invention relates more especially to latch-needles for knittingmachines of the class containing a skeleton cylinder which is arranged between the needle-cylinder and the cam-cylinder. Needles for this class of knitting-machines have been provided with enlargements on their heels, which come in to contact with the skeleton cylinder in order to keep the needle from tipping or working radially out of the needle-cylinder at their heel ends.

My invention consists in a knitting-machine needle having an applied collar to form lateral projections from its heel for cooperation with the skeleton frame of a knittingmachine of that type, the said collar being inserted in a saw kerf or cut made between the limbs of the heel of the needle next to its body and wound about and between the limbs of the heel substantially in the form of a letter S or figure 8.

o 1 have shown my invention applied as an addition to the round-stock projection of the Patent No. 576,172, dated February 2, 1897, and also as applied to a flattened heel of ordinary construction, both which construc- 5 tions require a modification of the heel in order to adapt the heel to receive my improved collar.

In the accompanying drawings, illustrating my invention, in the several figures of which like parts are similarly designated, Figure l is an elevation and projected crosssection of the round blank. Fig. 2 is an elevation and projected cross-section of the blank of Fig. 1 flattened and provided with the unreduced 5 heel portion. Fig. is an elevation of the blank of Fig. 2 prepared for the reception of the S or 8 collar. Fig. 4 is an elevation of a latch-needle comprising the invention of the patent before referred to and this present invention. Fig. 5 is a front elevation of the needle of Fig. 4;. Fig. 6 is a cross-section, en-

larged, taken in the plane of line 6 6, Fig.4,and looking in the direction of the arrow. Fig. 7 is an elevation and project-ed cross-section of a flattened blank of ordinary construction. Fig. 8 is an elevation of the blank of Fig. 7 prepared for the reception of the S or 8 col lar. Fig. 9 is an elevation of a latch-needle of ordinary construction supplied with the S or 8 collar. Fig. 10 is a cross-section, enlarged, taken in the plane of line l0 10, Fig. 9, and looking in the direction of the arrow. The blank d is produced from round wire or stock in any ordinary manner, and it is then flattened, as in Fig. 2, excepting that the portion 1) of its heel is left unreduced or unflattened and of the ordinary dimensions of the wire, so as to present lateral projections on both sides of the heel in accordance with the invention of the patent referred to. I find it advisable, in needles of fine gage especially, to apply additional projection to the heel in order to enable the needle to cooperate efficiently with the skeleton cylinder, and also to impart requisite strength to the heel to meet the strains put upon it. In order to apply a collar to the heel in such manner as to render its accidental displacement or loss impossible, I saw or cut away a portion of the stock between the limbs of the heel, as at c, Fig. 3, and then a strip or band of metal of proper thickness and width is passed through this opening 0 and its ends bent about the limbs of the heel in the form of a letter S or figure 8, thereby to form a collar 01, whereby such collar is firmly secured to the heel beyond the peradventure of accidental displacement or loss. As already stated, Figs. 1 to 6, inclusive, show this S or 8 collar applied to the unreduoed 9o portions of the heel forming the subject of the patent already referred to, and in Figs. 7 to 10, inclusive, I have shown the present invention applied to a latch-needle of ordinary construction. As shown in Fig. 8, the adjacent edges of the members of the heel are sawed or cut away at e and the collar d applied thereto, as before.

The S or 8 collar not only enables me to obtain in all gages the requisite lateral projections to cooperate with the skeleton cylinder but it also strengthens the heel of the needle and is united with the needle beyond the possibility of displacement or loss.

WVhat I claim is- 1. A.knittin;z-machine needle of the class described, havinga saw kerf or out made between the limbs of the heel neXt to the body of the needles, and a strip or band of metal inserted in said saw kerf or cut and its ends bent about the limbs of the heel in the form of a letter S or figure 8, and constituting a collar which is secured against accidental displacement and which affords the necessary lateral projection from both sides of the said heel and also strengthens said heel, substantially as described.

2. A knitting-machine needle, of the class ELMER is. NEWTON.
